Where are textbox default settings?

Dear OpenXml developers,

Open PowerPoint and insert a text box, I see in Font toolbar a font name, Calibri (Body), and a size, 18. Where come these default settings? After the pptx file is saved, does these settings go to any xml part of the the package, or these are settings from application not save to anywhere in the package?

Thank in advance,
Ed.

I believe these are application defaults. If they are saved (sometimes they are), they will be in 'ppt/presentation.xml' in 'lvl1pPr' of 'defaultTextStyle'.

Hope this helps!

Yes. Follow your direction, I change size into '2800':
('sz' attribute value at 'p:presentation/p:defaultTextStyle/a:lvl1pPr/a:defRPr')
and font into 'Impact':
('typeface' attribute value at 'p:presentation/p:defaultTextStyle/a:lvl1pPr/a:defRPr/a:latin').
Next time when I open the file in PowerPoint, both get applied. You are right that here is the place for default text box settings.

Thank you very much.
Ed.

Hi fwde,

Your reply is very helpful. Now, I know that 'lvl1pPr' in 'defaultTextStyle' is responsible for text box default setting. Thanks. BTW, could you please tell me, in parallel, what 'lvl2pPr', 'lvl3pPr'... 'lvl9pPr' are possibly used for? I am curious after I know what the first one is used for.

Thanks again,
Ed.

Those are paragraph levels. They are used to apply different styles to paragraphs, based on what level the paragraph is at. You will mainly see them used to distinguish what bullet characters/autonumbering types/indenting are applied to paragraphs.
